shell——for in

 

 

for 循环，数字

#!/bin/bash

echo "-----1-----"
for ((i=0;i<10;i++))
do
    echo $i
done

echo "-----2-----"
for i in 1 2 3 
do 
    echo $i
done

echo "-----3-----"
for i in {1..10}
do 
    echo $i
done

echo "-----4-----"
for i in `seq 1 10`
do 
    echo $i
done

echo "-----5-----"
for i in text3 text4
do
    echo $i.txt
done

for in 创建文件，并重复写入

反引号有意义！

#!/bin/bash

interpreter=`#!/bin/bash`

cd /home
mkdir testFor
cd testFor

for i in {1..10}
do 
    touch $i.sh
    echo $interpreter > $i.sh
done
